Parmalim is a religion that some people in Indonesia follow. Think of it like believing in a superhero, except instead of a superhero, they believe in a nice man named Guru Patimpus. Parmalim followers believe that Guru Patimpus helps guide them to have happy and good lives. They also believe that after they die, they will go to a really nice place called Puya, where they will live happily ever after. Parmalim followers follow certain rules, like being kind to others and not doing anything that will hurt someone else. They also have special ceremonies and prayers to show their love and respect for Guru Patimpus. Just like how you might sing happy birthday to someone you love, Parmalim followers sing songs to show their love for Guru Patimpus.
